SPINDLE-SUPPORT FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 666,252, dated January 15, 1901.

Application filed October 5, 1898.

To all wltont it may con/cerf@ Be it known that I, EPPA H. RYON, of Waltham, county ot' Middlesex, State of Massachusetts, have invented an Improvement in Spindle-Supports for Spinning-Machines, of which the fol lowing` description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

1o This invention relates to the production of an improved spindle-support, the object of the invention being to obviate undue gyration of the spindle when run at high speed.

Under one head of my invention the bolster having the bearings for the spindle has two yielding' points of connection with the spindle-rail, whereby the said bolster when it yields to the band-pull on the spindle will move laterally without any tendency to tip.

zo The bolster is mounted to turn about a vertical stud or post carried by the rail, said stud resting in a vertical passage made in a lateral extension of the bolster parallel to the usual chamber in which the pintle of the spindle stands and turns, and said stud is surrounded by a yielding packing or cushion. The upper l part ot' the lateral extension of the bolster receives and sustains a beari ng-ring, preferably mounted adjustably therein, said ring consti- 3o tuting a raceway on which may turn a series of balls constitutinga rolling lateral bearing, said balls also cooperating with a conical surface on the spindle at a point, as herein shown, above the point of junction of the whirl with the spindle. The whirl or a portion movable therewith is surrounded loosely with a movable lint or dust shield, which precludes the passage of lint or dirt to contact with the said balls.

4o Figure l shows in elevation a spindle in a bolster embodying my invention, said bolster, its case, and rail being in section; and Fig. 2 is a top or plan View of the spindle and its support.

The spindle-rail A has two holes d and d. The hole a receives loosely the shank b of the plate B, resting on said rail and having a hole b, which surrounds loosely the bolster support or pivot c, having a collar cl to bear on 5o the top of said plate B, the lower end of said support fitting loosely the hole ct of the rail Serial No.692,680. (No model.)

and having applied to its lower end a suitable clamping-n ut c2, bywhich said support is fixed in the rail at one side of the hole a, through which is extended the shank e of the bolster E, saidshank being shown as surrounded by an elastic packing h2, it being interposed between said shank andthe shank of the plate B.

The bolster is shown as of peculiar construction-7l. e., it presents a shank e, bored for the 6o reception of the pintle f of the spindle F, and a lateral extension e, supporting an overhanging ring-shaped arm e2. The upper end of the shank e has a liared cup e4, extended sufiiciently to enable thenose of an oil-can to be applied when it is desired to introduce oil in the chamber f2. The lateral extension e' is bored at e5 to t loosely over the support or vertical stud c, a yielding packingf3 being preferably applied to said support and inter- 7o posed between it and the interior of the bore e5, so that the bolster may yield, as required, to a limited extent under the pull of the usual driving-band in the groove of the whirlf4, attached to the spindle, the packing b2 sur- 75 rounding the shank e yielding at the same time, the movement of the bolster being about its support or stud c.

The overhanging part e2 of the bolster is of ring shape and threaded internally, as at e, 8o to receive the bearing g, shown as externally threaded and screwed into the threads of the bearin g-rin g. This ring has inner faces which constitute a raceway for the balls h, which constitute a rolling lateral bearing for the spindle at a point, as herein shown, just above the whirl, said spindle having at that point a conical projection f5, on which said balls rest and turn.

The lower extremity of the spindle'rests on 9o a ball or rolling bearing m, and by adjusting the ring-bearing in the overhanging part e2 of the bolster the proper tit or contact of the balls h with the ring and projection may be had. The upper end of the ring gis notched, as shown at 2, and one or the other of said notches is engaged by one end of a locking finger or spring 3, held in place by a suitable screw 4, said tinger holding the said ring in any position in which it may be put by adroo justment. The upper end of the ring g is chambered and receives a piece of packing m', which may have oil applied to it, said oil being given up slowly, as required, to just keep the balls wet.

The spindle F has applied to it in a detachable manner, as by a set-screw f8, a bobbinholding basefT, the lower end of said base i substantially meeting the said packing and keeping it down in place.

To the under side of the overhanging parts e2 of the bolster I have connected loosely by a screw'n a dust or lint shield n, it entering at one edge a groove 6 in the said arm. This shield embraces loosely the whirl f4, and as the band-pull on the whirl causes the spindle to be moved slightly laterally the said shield slides on said screw and acts always to keep dust or lint from getting into the ring and coming onto the balls.

During any lateral movement of the spindle due to the band-pull or to any uneven loading of the spindle the same in its movements is kept in its true vertical position, and the bolster` may also move slightly, as required,

about the vertical support or stud c to enable the spindle to be rotated at high speed without undue gyration.

I am not aware prior to this invention that the bolster has ever been permitted to turn about a vertical stud located at one side the spindle receiving opening of the bolster or that such a bolster has ever been adapted to move under the restraining inuence of elastic packing.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. A spindle-rail having a vertical stud, a bolster mounted loosely on said stud, a spini dle adapted to rotate in said bolster, and an adjustable plate surrounding the shank of said bolster loosely and having an ear engaging said stud, substantially as described.

2. Aspindle-rail havinga vertical stud surrounded by a packing, and a bolster mounted on said stud and embracing said packing, and a spindle in said bolster, a plate bored to re ceive a packing, a packing in said plate surrounding the shank of said bolster, substantially as described.

3. A bolster having a shank provided with a cup, a lateral extension provided with a bore parallel to the spindle-opening in said bolster, an overhanging arm containing a ring-bearing to constitute a ball-race; combined with a spindle located inside said bearing, balls interposed between said spindle and bearing, and a stud rising from the spindlerail and entering said bore, substantially as described.

4. A bolster having an overhanging arm provided to constitute a space in which may run a whirl,a ring-bearing detachably secured in said overhanging arm, the spindle and its whirl, and a conical projection located thereon below said rin g-bearing, and a bobbin-base holder located above said ring-bearing, combined with a series of balls interposed between said projection and the interior of said ring-bearing, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EPPA H. RYON.
